栓剂是由有疗效的药—主药和不起疗效的药—基質(赋形药)混合均匀通过栓模而制成。每颗栓剂中的主药重量与主药在栓剂模型中置換出相同体积的基質的重量之比,称为“置換价”。常用的基質为柯柯豆油。由于各种药品的比重不同,即使从同一栓模中制得的栓剂,其重量坯是有很大的差異,如果不进行计算,所制成的栓剂就一定不准确,因此必須先求出药品置換出柯柯豆油的数值。另一方面,当拿到一个不知大小的栓模时,也必須先求出置換价后才能制备栓剂。換算置換价还没有一个比較明确的公式。这样要 Suppositories are made from curative drugs that are mixed with a primary drug and a non-effective drug-matrix (excipient) through a plug mold. The ratio of the weight of the primary drug in each suppository to the weight of the primary drug displaced in the suppository model out of the same volume of the matrix is ​​called the “replacement price.” Commonly used substrate is Ke Ke soybean oil. Due to the different proportions of various medicines, the weight of the suppository prepared from the same suppository is quite different. If the suppository is not calculated, the suppository must be inaccurate. Therefore, the medicine must be obtained first Replace the value of Koocean soybean oil. On the other hand, when you get an unknown size plug, you must also find the replacement price before you can prepare suppositories. Converted replacement price is not a more clear formula. Like this
